Cisco 1760 router stays in rommon modus

I am having problems with a cisco 1760 router. When I turn the router on I am getting stuck in rommon mode. When I enter the command: "boot flash:c1700-sv8y7-mz.123-11.T3.bin" , the router will boot the ios image. But when i turn the router off and on, it will return to rommon mode. I have tried the following commands in rommon mode:

rommon 1 > confreg 0x2102

rommon 2 > reset

or

rommon 1 > confreg 0x142

rommon 2 > reset

without results. I get the following errors:

Re: Cisco 1760 router stays in rommon modus

I would recommend posting in the netpro forums about this.

This site is for the Cisco Small Business Pro routers.

For your problem though, you might try looking at your boot system command in your running config to make sure that it is accurate.
